The SRM-727II is an exclusive driver unit (amplifier) from the Japanese audio giant, STAX. This driver unit produces a vivid and dynamic sound thanks to the Non-Feedback Output Stage and high-quality parts used.

The electrodes and high-polymer film diaphragm give you a balanced sound while the bypass connection let you use the SRM-727II just as an amplifier for all your STAX earspeakers. A direct switch makes sure that there is no duplication of volume control.

  • Your Earspeakers’ Best Friend

    The SRM-727II has been exclusively designed for earspeakers characterized by their wide high dynamic range and outstanding operating features. Thus, pair your headphones with the SRM-727II and enjoy the best that the world of music has to offer.

    First Non-Feedback Output Stage

    The SRM-727II features the first-ever Non-Feedback (NON-NFB) output stage in a STAX driver. It also has a large current emitter and Class-A amplification circuit. This gives you a vivid and dynamic sound over a wider frequency range.

    Balanced Music

    The SRM-727II has electrodes on either side of an extremely thin high-polymer film diaphragm. This and the XLR input lets you listen to a balanced sound without a conversion circuit.

    Bypass Connection
    Now connect your SRM-727II to any other pre-amplifier, integrated amplifier and receiver or passive volume control with ease. All these need is a pre-out. A direct switch on the driver ensures that there is no duplication of volume control.

    Quality in Every Detail

    Each part of the SRM-727II has been selected with care. A low noise Field-Effect Transistor (FET) and two-stage amplifying circuit are used at the input stage. This lets you listen to pure and natural music.

    Beauty at its Best

    The SRM-727II has a newly designed front panel. It is crafted with rounded corners and has been given a brushed finish for a sleek look. This driver is available in 2 colours—Black and Silver.
